- The electrical and magnetic properties of $Fe_{0.5}A_{0.5}$ alloys are presented, where the A corresponds to various compositions of the elements: A = (Al, Si, V, Cr, Co, Ga, Ni, Ge). The system is closely related to the known family of high entropy alloys. The samples were synthesized by arc melting and/or melt spinning technique and exhibit a regular type of crystal structure. Lattice parameters are systematically smaller than the estimates based on metallic radiuses of the elements. Temperature dependences of resistivities show maxima for some compositions. This behavior is consistent with results of electronic structure calculations, where a low density of states at the Fermi level were predicted. Also the measured magnetic moments are in good agreement with results of calculations. It is thus presented that some physical properties can be designed by appropriate choice of the chemical composition within the same simple structure.
